IMPROVEMENT IN MANGLES.

Specification forming part of Letters Patent N 0. 220,866,

To all 'whom 'it may concern:

Be it known that I, CEAnLEs timore,

dated October 21, 1879; application filed July 10, 1879.

REEsE, of Balin the county of Baltimore and State of Maryland, haveinvented certain new and useful Improvements in Mangles, of which thefollowing is a specification.

My invention relates to that class of man gles wherein the cloth orclothing' to be smoothed or ironed is wound upon a roller laid upon astationary bed or table and rolled back and forth underapendulously-moving platen,

which is so hung that its entire weight in operation comes upon theroller.

this description is the subject of Apri115,1s79,u0.214,44s.

A mangle of my patent of My present invention consists in certainimprovements in the mechanism platen, and for sustaining it when in the.contours of the surfaces and. bed, whereby the machine for lifting thelifted, and of the platen can be operated with greater ease, all as willbe hereinafter fully set forth.

In the accompanying drawings, Figure l is a vertical cross-section is aview in g-lever,

section, showform ofthe bed and platen surframes.

Gis a removable roller, around which the cloth or clothing to beoperated upon is wound, and which in operation is placed upon the bed;and D to or between the side frames is a platen, so hung or connectedthat it is constrained to a'pendulous movement over the bed, its entireweight in operation coming upon the roller O.

The platen is capable of heilig as not to bear upon the roller,

suflicient to give the necessary lifted up so has a weight pressure tothe cloth or clothes, and is or may be provided with a suitable handleby which to swing it.

From the upper portion of the platen project, on its opposite sides, twostuds or shaft ends, a a, which enter vertical, or nearly vertical,slots or grooves b b in or through the side frames, one slot being ineach frame. The platen is thus constrained to a swinging or pendulousmovement, while, unlike a pendulum, its weight is not normally upheld atthe center, from which it swings, but is borne by the roller O, which isplaced under it. It is also capable of some vertical play to accommodaterolls of different diameters, and to permit of its being lifted off theroller.

So far as described there is no present novelty in my machine, theseparts and their combinations being shown in my aforesaid patent of April15, 1879.

In the drawings I have shown the machine as of selfeontained andportable form 5 but, if preferred in any particular case, it may bebuilt permanently into the laundry or other room or building where it isto be used, the walls of the sametaking the place of the frames A A, thebed B being fixed to the door, and the slots b b formed in bracketsdependent from the ceiling or attached to the walls.

lf desired, the hed, platen, or roller, or any two or all of them, maybe heated either by making them hollow and introducing steam, or by theuse of gas, or in any other known and practicable way.

In my present construction the lifting device consists of a lever, or,preferably, a pair of levers or double lever, E, fulcrumed to or betweenthe side frames, A A, and arranged in a plane parallel with the latter,its short arms taking under the studs a a, so that by pulling down thelong arms of the leverits short arms lift the platen, its studs a apassing up in the slots or grooves b b.

In case a single lever, E, is used it should be arranged centrally, orabout midway between the side frames, and might be fulcrumed on across-shaft or other provision 5 but I prefer to use two levers, one ateach side of the machine, between t e platen and the side frames, and toconnect 'them by a horizontal bar or handle,

c, as shown. This construction gives greater steadiness and strengththan when a sin glelever is used. lf preferred, the levers may liearranged just outside of the side frames.

It is important that some means should be provided for sustaining theplaten when it has been raised,and it is desirable that this should beaccomplished automatically, or as part of or continuation of theoperation ot' lifting.- I prefer to attain this result by theconstruction shown in the first four figures of t-lie drawings. Theslots or grooves b b are deflected to one side, either abruptly or, as Iprefer, in a gentle curve, until a substantially-horizoiital position isgiven to their extremities. In the lower side of this horizontal portionof each slot is formed a rest or bearer, d, which re ceives and upholdsthe stud a of the platen when the latter has been raised, as clearlyshown in Fig. 3. Just iii front of the rest d, or between it and thevertical portion of the slot b, is a slight rise or elevation, e, toprevent the unintentional escape of the stud from the rest.

The fulcruiiis of the lifting lever or levers are arranged on the saineside ofthe slots b I that the latter are deflected toward, andpreferably in a lower plane than the upholdingrests d d. By thisarrangement the depression of the long arms of the levers first liftsthe studs a a through the vertical portions of the slots b b, and thennioves them laterally over the elevations e e onto the upholdingrests dd. IIere they will remain of themselves, as the entire weight of theplaten niust be lifted a short distance, while the studs pass back overthe elevations e e before the platen can descend.

To effect the lowering or descent of the platen, I provide the short armofthe lever E with a projecting toe,j', arranged above thelifting-surface, and of such length as to contact with the stud, and, as.the handle of the lever is lifted, to push it along until it passesover the elevation c and reaches a portion of the slot suftcientlyinclined to cause it to complete the descent of itself. l prefer toleave sufficient space between thc end of the toe f and the extremity' gof the lever to enable the latter to clear the studs after they arelowered into place, when the long arm of the lever is raised, so thatthe latter may be thrown up vertically out of the way of the operator,as shown in Fig. 1 but if this capability on the part of the lever isnot deemed desirable, the space between f and g may be t'illed up,leaving only a slot for the reception of the stud a.

In Fig. 5 I have shown a nioditication of the above-described liftingdevice. Instead of forming the rest d and elevation e in a deiiectedportion of the slot b, I form them upon the lifting-lever E, itslifting-surface being nearest the fulcruin, a nose or elevation, c,next, and a concave rest, d, toward its extremity. With these parts uponthe lever, a simple straight slot may be used, as shown. The

operation of this is essentially the saine as that of the otherform-namely, that the dcpression of the long ariii of the lever firstlifts the platen, and then so suspends it that it cannot descend untilthe lever is moved back.

As heretofore constructed niangles of this character have had the facesof the bed and platen of suoli forni that the center of oscillation ofthe platen (answering to my studs a a) remained, for a uniform diameterof roller, at the same point during the entire swing or oscillation ofthe platen. While this constructioii answers admirably for manypurposes, the platen has not under some circumstances sufficienttendency to return to its vertical or central position after being swungout there from to adapt it to all requirements.

I deem it desirable that the platen should have at all times a decidedtendency to assume the said vertical position, as it renders theoperation of the machine much easier than when it has to be brought backby the operator.

I accomplish the desired elect by so shaping the .faves of the bed andplaten relatively' to each other that their edges, lettered h h in thedrawings, approach normally nearer each other than do their centers,which are lettered The effect of this construction is that in theoperation of the machine the stud or pivot a will be at its lowest pointwhen the platen descends vertically, and will graduallyV rise as theplaten is swung outward to either side.

I consider it desirable that one or both of these surfaces be fiat orplane, this being the simplest and cheapest form.

In Fig. 1 I have shown the platen provided with a plane face, and thebed with a concave curved face, which is the preferred forni; and inFig. 5 I have shown a modification, being a reversal of the surfaces,the platen being concave and the bed tiat; or, if a flat face for eitherbed or platen be deemed undesirable in any particular case, both facesmay be curved, as shown iii Fig. 6; but they must be so curvedrelatively that the studs a a will rise as the platen is swungin eitherdirection from its central position of rest.

l claim as my invention- 1. The combination of the side frames, A A, andtheir slots b b, the platen D and its studs a a, and the lifting-lever Ewith an upholding rest or bearer, d, for the stud when lifted,substantially as set forth.

2. The side frames, A A, provided with slots b b and rests or bearers dd, in combination with the platen D and its studs a a, and withj alifting-lever, E, substantially as set ort 3. A mangle consisting of theside frames, A A, each provided with a slot, b, and rest d, the hed B,roller C, platen D, provided with studs a a, and the lifting lever orlevers E, combined and arranged to operate substantially as set forth.

4. A mangle having a xed bed, B, and pendulous platen D, between whosefaces a, roller, C, is received, said faces approaching nearer eachother at their edges h h than at their centers i i, whereby the centerof oscillalLion ofthe platen is caused to rise as the platen is swung toeither side of its normal position of rest, substantially as and for thepurposes set forth.

In' Witness whereof I have hereunto signed my name in the presence oftwo subscribing witnesses,

CHARLES REESE.
